Read the article of the DIY battery tab resistance fine-spot welder here:
http://www.avdweb.nl/tech-tips/spot-welder.html


Because the electronics and software is too complicated for many people I have made a printed circuit board.

Questions about the spot welder controller can be asked in this topic.

Interesting.  Just been looking over the software Here

Just wondering what this bit is supposed to be doing.

I don't quite understand why you are shorting the two big wires from the transformer. Isn't one end supposed to go to the ground clamp?

Yes that is weird, long story, but fixed now.

It is not shorted.

That's an unusual arrangement.
Usually the two arms are diametrically opposed, either vertically or horizontally, so that they can compress the work parts together before sending the current through them.  I can't see how your welder would work without pinching the two work parts together.
See http://www.tool-net.co.uk/p-363291/clarke-csw6t.html?gclid=CNauroS6zMMCFU7KtAodBjgAHQ  for an example.

This electrode arrangment is used for battery tabs welding or other welding tasks, where the access is limited to one side only. Search for battery tab welding and you 'll see why is this done like this.

Hello Albert!
My name is David and I was curious where i can find the <Switch.h> library and the <Albert.h> library.
I found the <Streaming.h> library and I am assuming that the <Arduino.h> library is already installed with my Arduino software program I recently installed on my laptop.  Thank you in advance for your help!!
P.S. I think your spot welder is awsome!!!! Kudos & Accolades!!!

interesting.    what is the typical amp load and what thickness of metals can this handle ?


I have wanted to weld battery tabs, but since it is so rare, just buy them pre-welded.

also  wanted to make/weld thermocouples from raw thermocouple wire.

can't wait for the youtube on this.

You can see here the Spot welder opposed configuration

The series configuration spot welding is not very common, but always used for welding batteries.

I mounted the electronics for the spot welder, I turned, but I always 220 V on output to the transformer. I checked and installed all components correctly.It has already happened a problem like this?
Thanks.
